Abstract

The structure, morphology and mechanical properties of polypropylene-nanoclay composites containing 1 to15 wt.% nanoclay was investigated. Combination of wide-angle x-ray diffraction (WAXD) and transmission electron microscopy (TEM) was used to determine nanocomposite morphology. Mixture of intercalated and exfoliated morphology was observed for all the samples. Samples with 1 to 5 wt.% clay showed shear induced orientation of clay platelets in the surface region of the molded bars. Glass transition temperature slightly decreased due to the plasticizing effect of additives. At higher weight percentage reinforcement (10–15 wt.%), up to 67 % improvement in tensile modulus is observed. Breaking energy was significantly improved for samples with up to 2 wt.% nanoclay additives. With further increase in nanoclay weight percentage, failure mode shifted from ductile to brittle. Increase in exclusion of clay additives at the boundary of spherulites and segregation of clay platelets were observed for samples with higher weight percentage of clay additives.
